  • the bumpers 100 and 200 shown in FIGS. 6 (a) and 6 (b) are first and second comparative examples.
  • the whole bumper is made of steel as in the first comparative example.
  • the sectional shape of the bumper 200 is almost the same as that of the bumper 1a of the first example but differs from the first example in that an intermediate member 206 having an "H"-shaped sectional shape penetrates not only a front flange 202 but also a rear flange 203.
  • the bumper 200 is 150 mm high and 65 mm wide. In this analysis, as shown in the following Table 3, each value in the case where the thickness of steel is 1.4 mm in each comparative example and in the case where the thickness of steel is 2.0 mm in each comparative example was calculated.
  • each part of the first to fourth examples used in this analysis is as shown in the following Tables 1 and 2.

  • each value in each of the cases where the thickness of the webs made of aluminum alloy is 2.0 mm, 3.0 mm, and 3.6 mm was calculated.
  • each value in the cases where the thickness of the webs made of aluminum alloy is 3.6 mm was calculated.

  • the ultimate moment ratio per weight ratio is improved compared to the first comparative example.
  • the ultimate moment ratio per weight ratio is improved compared to the first and second comparative examples. That is to say, in the first example, in the case where the intermediate web 6 is made of aluminum alloy of 7000 series and the thickness of the intermediate web 6 is 3.0 mm or 3.6 mm, the bending strength per weight is improved efficiently. In the second example in which all of the webs (upper web 4, lower web 5, and intermediate web 6) are made of aluminum alloy of 7000 series, the bending strength per weight is most improved.
  • the ultimate moment ratio was below 1.0. That is to say, it is shown that in the first example, in the case where the intermediate web 6 is made of aluminum alloy of 7000 series and the thickness of the intermediate web 6 is 2.0 mm, and in the case where the intermediate web 6 is made of aluminum alloy of 6000 series and the thickness of the intermediate web 6 is 3.6 mm, the weight can be reduced compared to the first and second comparative examples, but the bending strength cannot be improved.
  • the ultimate moment ratio per weight ratio is improved compared to the first and second comparative examples. That is to say, it is shown that in the third and fourth examples, the strength per weight is improved efficiently.
  • the density of the aluminum alloy of 6000 series or 7000 series is 2700 kg/m 3 to 2800 kg/m 3 . Therefore, compared to the case where the whole bumper is made of steel 1.4 mm thick, in each example, the value of the right side of Expression 6 is about 4.1.
  • the thickness of the aluminum webs is smaller than about 4.1 mm, and Expression 6 is satisfied.
  • the weight ratio of each example is about 1 or less.
  • FIG. 10 is a plot of ultimate moment ratio versus A value about each example based on Table 4.
  • the A value is below 0.5 in the first example, that is to say, in the case where the intermediate web 6 is made of aluminum alloy of 7000 series and the thickness of the intermediate web 6 is 2.0 mm and in the case where the intermediate web 6 is made of aluminum alloy of 6000 series and the thickness of the intermediate web 6 is 3.6 mm, the ultimate moment ratio is below 1. That is to say, in these cases, sufficient strength cannot be ensured. For this reason, in the case where a material other than steel is used, it is preferable to select such a material that the A value is 0.5 or more.
  • the bumpers 1 (bumpers 1a to 1d) of this embodiment have a front flange 2 and a rear flange 3 made of metal and forming the front surface and the rear surface, and an upper web 4 and a lower web 5 made of metal and forming the upper surface and the lower surface. Between the upper web 4 and the lower web 5, an intermediate web 6 made of metal is disposed. By this intermediate web 6, two hollow spaces 7 and 8 are formed within the bumper 1. At least one of the upper web 4, lower web 5, and intermediate web 6 is made of a material other than steel. As the material, a material satisfying the above Expression 1 is selected. Therefore, at least one of the webs is made of a material by which the buckling strength per weight can be easily ensured.
  • the intermediate web 6 is made of a material other than steel. Of the webs, the intermediate web 6 is disposed in the middle, and therefore the balance of strength of the whole bumper is kept by making the intermediate web 6 of a material other than steel.
  • the upper web 4, lower web 5, and intermediate web 6 are all made of a material other than steel. Therefore, the overall weight can be reduced further.
  • reinforcing plates 31, 32, 41 that reinforce the corners of the outer shape member 11 are provided. By these, the bending durability of the whole bumper can be improved.
  • a material other than steel is selected so as to satisfy Expression 6, and therefore the weight can be reduced to less than that in the case where the whole bumper is made of steel.
  • a material other than steel is selected such that the A value defined by Expression 7 is 0.5 or more, and therefore the bending durability can be ensured.
  • the webs are made of aluminum alloy, the webs may be made of another metal material.
  • the joining method is not particularly specified, a method having sufficient joining strength, such as welding, bonding, or bolting, can be used.
  • the present invention can be used as a bumper structure attached to the body of an automobile.
